If you've downloaded or had the Android 2.3.6 update pushed to your AT&T, T-Mobile, or unlocked Nexus S recently without issue, consider yourself lucky. None of this applies to the Nexus S 4G on the Sprint network.

While we reported that the update was breaking Wi-Fi and USB tethering initially, it seems something much, much worse is happening to some users who have received 2.3.6 OTA.

If you check out this Google thread, you'll see a number of poor souls have had all cellular connectivity stripped from their devices after updating.

WARNING: This file is only for the Sprint Nexus S 4G. To flash the update, the phone must be stock - that means no custom ROMs. Rooted handsets are OK, though this might reset root permissions (you just need to re-root). We've included a link to a full, flashable ROM which will probably require a wipe, as well.

If you find yourself still without the Android 2.3.7 (GWK74) update for your Sprint Nexus S 4G, have no fear - we're here to help.

As disappointing as it may be to see the Nexus One - Google's first officially anointed developer phone - still getting Froyo-based updates, that's exactly what just happened. According to several Android Central forums members, a 558kb update to Android 2.2.2 (or build number FRG83G) is currently rolling out over the air to the N1, bringing "important bug fixes" with it.

In related news, the Samsung-built Nexus S - Google's second developer phone - also received an update today, though this one is Gingerbread-based.
